From 27c3944874a034975d23722b10d6d7e6b7dd930d Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.org>
Date: Mon, 18 Apr 2016 11:56:53 +0100
Subject: [PATCH] scripts/mkknlimg: Append a trailer for all input
Now that the firmware assumes an unsigned kernel is DT-capable, it is
helpful to be able to mark a kernel as being non-DT-capable.
